Yes, that's a good average recommendation. The actual frequency recommendation (if you really want to get deep into the technical side of it), is for smartphone users with Lithium Ion batteries in their phones (all newer phones - which is most of us now), to do the training after 40 total 100% charge and discharge cycles (or 4,000% of total battery usage). Since we NEVER use the entire 100% from full to 0% (DO WE???? :icon_ devil
, and we never let the battery drain to 0% in any case (DO WE???? :icon_ devil
, you would have to keep track of every percentage of use and add them up, then add up the percentage of charge, and when the two total a ratio of 1 to 1 and exceed 40 total, then the training would be done.
For example, let's say I use the phone 50% each day, and charge back to 100%. So if I need 40 100% cycles, that would be 80 days for me, or two months and 20 days (40/50%=80). But let's say I use it on a consistent basis at 80% daily and then charge to 100%. Well then I'd need to do the training after only 50 days, or one month and 20 days (40/80%=50).
It gets MUCH MORE DIFFICULT to keep track if your usage pattern changes from day to day (as nearly all of ours do), so the recommendation of 2 months for the RAZR is based on the expectation that most RAZR users are going through the bulk of, if not nearly all of the usable charge and recharging to 100% on a daily basis, which would point to about 50 days per 4,000% cycle.
For RAZR MAXX users, since the battery is nearly twice the size, I simply took the 50 day average and doubled it to 100 days, and considering it's not quite twice the size (3,300mAh versus 1,780mAh), or actually about 79% of double the RAZR's battery, take 100 and multiply by 79%, and you get 79 days. Since 79 is closer to 90, I chose 3 months as the upper range for frequency of 4,000% cycles.
But you didn't want to get too technical, now did you?
